3" Lascotite PVC Compression Coupling, 21130

Duplex Seal – The compressive force from the thread cap applies concentrated pressure at two key sealing points. Because both the cap and body are recessed to hold the compression gasket, fluid is prevented from entering the cap’s thread cavity.

Wide Gripping Area – This compressive action also delivers strong, uniform gripping across a broad section of the pipe, helping resist longitudinal pull-out.

Easy Pipeline Repairs & Modifications
LASCOtite™ fittings simplify pipeline adjustments. Couplings can be quickly installed between butted pipe ends without the need for extra clearance. Just slide the coupling fully over one pipe, realign the ends, center it, and tighten the nuts.

Ideal for: Adding new branch lines, test connections, service joints, temporary piping

LASCOtite™ fittings are also reusable and removable. No threading or solvent welding is required. Gaskets ensure a reliable, leakproof compression seal.

Built to Standard – LASCOtite™ wall thicknesses meet or exceed Schedule 40 fitting requirements as specified in ASTM D-2466.
